[0027] In some assembly equipment, it is necessary to assemble one workpiece with another, which requires first positioning and fixing one of the workpieces to be processed. Different workpieces have different sizes. In order to adapt to workpieces of different sizes, the positioning mechanism needs to be adjusted and positioned according to different workpieces, which consumes a lot of manpower and resources and results in low production efficiency.

[0028] LCM (LCD Module) is widely used in various electronic devices such as smartphones, tablets, and automotive screens to convert image signals into visible images or text information. The production process of LCM involves the assembly of multiple precision components, including FPC (Flexible Printed Circuit), PCB, backlight, bonding cover, and structural components. In traditional LCM production processes, the PCB needs to be bonded to the FPC. Before bonding, the PCB is positioned and fixed, and then pressed down by a pressure head to make the PCB and FPC fit tightly together, completing the electrical connection and physical fixation. Since the PCB serves as the mounting base for electronic components and integrates different electronic components, and the layout and arrangement of different components vary depending on the PCB model, different positioning positions need to be adjusted for different PCB models during production to ensure that the PCB can be accurately positioned. In other words, every time a new PCB model is changed, frequent debugging and positioning are required, which consumes a lot of manpower and resources and reduces production efficiency.

[0029] This utility model proposes a positioning mechanism and a pressing device.

[0030] Please see Figure 1In one embodiment of the present invention, the positioning mechanism includes a mounting base 100, an adsorption assembly, and an adjustment assembly 300. The adsorption assembly includes two adsorption elements 200, which are slidably disposed on the mounting base 100 and are used to adsorb and fix the workpiece to be processed. The adjustment assembly 300 is disposed on the mounting base and connected to the adsorption elements 200. The adjustment assembly 300 is used to drive the adsorption elements 200 to slide on the mounting base 100 along a first direction to adjust the spacing between the adsorption elements 200.

[0031] In the technical solution of this utility model, the positioning mechanism includes a mounting base 100, on which an adsorption element 200 for adsorbing the workpiece to be processed is provided. An adjustment component 300 is driven to connect with the adsorption element 200 so that the adsorption element 200 moves on the mounting base 100 along a first direction, thereby adjusting the distance between the two adsorption elements 200 along the first direction to adapt to different types of workpieces to be processed, reducing the debugging time of the position of the adsorption element 200, facilitating faster and better positioning of the workpiece to be processed, improving production efficiency, and preventing the workpiece to be processed from shifting when it is pressed with the FPC board, thus affecting the pressing accuracy.

[0032] In one embodiment, the mounting base 100 serves as the mounting substrate, and its shape and material are not limited. To ensure the stability of the positioning mechanism installation, metal materials such as alloys can be selected. An adsorption component 200 is provided on the mounting base 100. The workpiece to be processed may include, but is not limited to, a PCB board. The following description uses a PCB board as an example. To facilitate the mounting of the PCB board, a plurality of screws are provided on the PCB board, and the plurality of screws are spaced apart. The distance between the screws on different models of PCB boards is different. The adsorption component 200 is provided to adsorb the screws. By setting two adsorption components 200 to adsorb one screw each, the PCB board and other workpieces to be processed can be positioned. The distance between the two adsorption components 200 is adjusted by adjusting the component 300. The adsorption component 200 can adopt vacuum adsorption, that is, the adsorption component 200 adopts a vacuum suction cup. The vacuum suction cup covers and adsorbs the protruding screws on the PCB board, that is, the screws provide precise positioning points. Compared with adsorbing blank positions on the PCB board, the operation time is reduced and the work efficiency is improved.

[0033] In one embodiment, the adjusting component 300 can be a bidirectional cylinder, that is, piston rods are provided at both ends facing opposite directions, and each piston rod corresponds to an adsorption element 200. The bidirectional cylinder drives the corresponding adsorption element 200 to move away from or towards another adsorption element 200, that is, the two adsorption elements 200 move closer to or further away from each other to accommodate the distance between two screws on different PCB boards. The adjusting component 300 can also be a linear drive component such as a cylinder, hydraulic cylinder or electric telescopic rod. Each adjusting component 300 is connected to one adsorption element 200 to adjust the distance between the two adsorption elements 200. No limitation is made here.

[0034] In one embodiment, a photoelectric sensor for detecting the position of the adsorption member 200 can also be provided on the mounting base 100 to improve the accuracy of position adjustment.

[0035] In an embodiment of this utility model, the adjustment component 300 includes:

[0036] The connecting seat 310 is slidably mounted on the mounting seat 100 along the second direction;

[0037] A connecting rod 320 is provided for each adsorption element 200. One end of each connecting rod 320 is rotatably connected to the connecting seat 310, and the other end of each connecting rod 320 is rotatably connected to the corresponding adsorption element 200.

[0038] The drive structure 330 is driven to connect to the connector 310 to drive the connector 310 to move along the second direction on the mounting base 100 so that the adsorption members 200 move closer to or further away from each other.

[0039] Please refer to Figure 1In this embodiment, the second direction is vertical. A slide rail extending vertically is provided on the mounting base 100, and a corresponding sliding block is provided on the connecting base 310. The sliding block is slidably connected to the slide rail. The driving structure 330 causes the connecting base 310 to slide vertically on the mounting base 100. The connecting base 310 is connected to the adsorption element 200 via a connecting rod 320. Each adsorption element 200 corresponds to one connecting rod 320. The two ends of the connecting rod 320 are rotatably connected to the adsorption element 200 and the connecting base 310 respectively via a rotating shaft. The connecting base 310 is located on the centerline between two adsorption elements 200. When the connecting base 310 moves towards the adsorption element 200 in the second direction, any... One end of the connecting rod 320 away from the connecting seat 310 moves away from the other connecting rod 320, thus driving the two adsorption components 200 to move away from each other. When the connecting seat 310 moves upward along the second direction away from the adsorption components 200, it drives the end of the connecting rod 320 away from the connecting seat 310 to move towards the center, thus driving the two adsorption components 200 to move closer to each other. In other words, regardless of the type of PCB board, as long as the distance between the two adsorption components 200 is adjusted according to the distance between the screws, the adsorption and positioning of the screw position can be achieved. This avoids having to find empty positions for each PCB board and then adjust the position of the adsorption components 200, shortening the positioning time and improving the processing efficiency.

[0040] In one embodiment, the connecting rod 320 is a single unit, or the connecting rod 320 is segmented, including multiple rods, with adjacent rods 320 connected by nuts to adjust the length of the connecting rod 320.

[0041] In one embodiment, the drive structure 330 may be a linear drive component such as a cylinder, hydraulic cylinder, or electric telescopic rod, and there is no limitation herein.

[0042] In an embodiment of this utility model, the drive structure 330 includes a drive motor 331 and a lead screw 332. The lead screw 332 extends along a second direction. The drive motor 331 is driven to rotate the lead screw 332. The lead screw 332 passes through the connecting seat 310 and is threadedly connected to the connecting seat 310 to drive the connecting seat 310 to slide along the second direction on the mounting seat 100.

[0043] Please refer to Figure 1The lead screw 332 extends along the second direction and is threadedly connected to the connecting seat 310. The lead screw 332 is driven to rotate by the drive motor 331, causing the connecting seat 310 to move along the length direction of the lead screw 332. In one embodiment, the drive mechanism also includes a connecting plate, which is fixedly connected to the connecting seat 310 by threaded fasteners. A mounting nut is fixed on the connecting plate. The lead screw 332 passes through the mounting nut and the connecting plate and is threadedly connected to the mounting nut. By rotating the lead screw 332, the mounting nut, the connecting plate, and the connecting seat 310 can move along the length direction of the lead screw 332. The connection plate facilitates flexible adjustment of the positions of the lead screw 332 and the drive motor 331, making reasonable use of space.

[0044] Please refer to Figure 1 In one embodiment, the drive structure 330 further includes a transmission assembly. The drive motor 331 drives the lead screw 332 through the transmission assembly. The transmission assembly includes a synchronous belt 333, a driving pulley, and a driven pulley. The output shaft of the drive motor 331 is coaxially connected to the driving pulley and rotates synchronously. The driven pulley is coaxially connected to the lead screw 332 and rotates synchronously. The transmission belt connects the driven pulley and the driving pulley. That is, through the transmission of the synchronous belt 333, the power of the drive motor 331 is transmitted to the lead screw 332, causing the lead screw 332 to rotate, thereby driving the connecting seat 310 to move in the second direction. The diameter of the driven pulley is larger than the diameter of the driving pulley.

[0045] In an embodiment of this utility model, the positioning mechanism further includes a slider 400, and each adsorption member 200 slides on the mounting base 100 along a first direction via the slider 400. The end of the connecting rod 320 away from the connecting base 310 is rotatably connected to the slider 400.

[0046] Please refer to Figure 1 The mounting base 100 is provided with a guide rail on the side facing the slider 400. The guide rail extends along the first direction. The slider 400 corresponding to each adsorption component 200 is slidably mounted on the guide rail. The end of the connecting rod 320 away from the connecting base 310 is rotatably connected to the slider 400. Through the movement of the connecting base 310 and the connecting rod 320, the slider 400 slides along the second direction. The cooperation between the slider 400 and the guide rail reduces the sliding resistance and allows the adsorption component 200 to move along the predetermined direction, avoiding deviation and affecting the adsorption accuracy. Specifically, the adsorption component 200 is located below the slider 400 to facilitate the adsorption of PCB boards.

[0047] In the embodiments of this utility model, please refer to Figure 2The positioning mechanism also includes detection sensors 500, which are located on the side of the sliders 400 facing the PCB board. Each slider 400 is equipped with a detection sensor 500. The detection sensors 500 are used to detect whether the adsorption component 200 has successfully adsorbed the PCB board, thereby improving processing efficiency. The detection sensors 500 can be photoelectric sensors, emitting infrared light in the direction of adsorption by the adsorption component 200 to detect whether the adsorption component 200 has adsorbed a workpiece such as a PCB board. If the infrared light is reflected, it proves that the PCB board has been successfully adsorbed. The detection sensors 500 can also employ visual inspection, etc., without limitation.

[0048] In an embodiment of this utility model, the mounting base 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 extends along a first direction, and the second bracket 120 extends along a second direction, with the first bracket 110 and the second bracket 120 being perpendicular to each other. The connecting base 310 is slidably disposed on the second bracket 120 and slides along the second direction, while the slider 400 is slidably disposed on the first bracket 110 and moves along the first direction.

[0049] Please refer to Figure 1 The first bracket 110 and the second bracket 120 are vertically arranged. The guide rail is arranged on the first bracket 110 and extends in the horizontal direction. The slider 400 is slidably arranged on the first bracket 110. The second bracket 120 is vertically arranged and is provided with a guide rail extending in the vertical direction. The first bracket 110 and the second bracket 120 are separate and vertically arranged, which reduces the weight of the overall structure and facilitates lightweighting.

[0050] In the embodiments of this utility model, the adsorption component 200 is configured as a magnetic structure. The magnetic structure can be made of a magnet, which is used to magnetically attract screws on the PCB board. The magnetic attraction can greatly shorten the adsorption and release operation time, improve production efficiency, and avoid damage to the PCB board by magnetic force adsorption.

[0051] In one embodiment, the adsorption component 200 is configured as an electromagnetic suction head. When the electromagnetic suction head is energized, it generates a magnetic field and is brought close to the PCB board to attract the screw, thereby positioning the PCB board. When the PCB board and the FPC board are pressed together, the adsorption to the PCB board can be quickly and accurately disconnected by turning off the power, so that the PCB board can be detached from the electromagnetic suction head. Without manual operation, the adsorption and release process can be automated and highly efficient, reducing waiting time and improving production efficiency.

[0052] This utility model also proposes a pressing device, including a base, a pressing drive component 20, a pressing head module 30, and a positioning mechanism. The specific structure of the positioning mechanism is as described in the above embodiments. Since the positioning mechanism adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. Please refer to... Figure 2 The positioning mechanism is slidably mounted on the base and slides along the second direction on the base; the pressing drive 20 is mounted on the base; the pressing head module 30 is used to press the PCB board waiting to be processed. The pressing drive 20 is driven to the pressing head module 30 to drive the pressing head module 30 to slide along the second direction after the positioning mechanism adsorbs the PCB board, so that the PCB board and the FPC board and other mating parts are pressed together. The screws of the PCB board are adsorbed by the positioning mechanism, and then the PCB board is pressed down by the pressing head module 30, which improves the processing efficiency of LCM. The pressing drive 20 adopts linear drive components such as cylinders and hydraulic cylinders. The pressing drive 20 drives the pressing head module 30 to press down. The pressing head module 30 includes a pressing head body and a heating tube on the pressing head body. The heating tube is used to generate heat to heat the pressing area to soften the adhesive on the surface of the PCB board and FPC board, so that it can better fill the small gap between the PCB board and FPC board, fit tightly, achieve a firm bond and electrical connection, and improve the reliability of the connection.
